The line graph shows the amount of money Bryan spent from January to June.
- Of the amount Bryan spent in May, $108 was spent on food and the remaining amount was spent on transport. How much did he spend on transport in May?
- In which month did Bryan spend $160 less than the previous month? Give your answer in this format. (Eg Jan)
(a)
Amount that Bryan spent in May = $480
Amount that Bryan spent on transport
= 480 - 108
= $372
(b)
To find a decrease in a line graph, look for a decreasing slope.
The 2 decreasing slopes are from March to April and April to May. Now, find the month when Bryan spent $160 less than the previous month.
Amount that Bryan spent in March = $820
Amount that Bryan spent in April = $660
Amount that Bryan spent in April less than March
= 820 - 660
=
$160 (✓)
Amount that Bryan spent in April = $660
Amount that Bryan spent in May = $480
Amount that Bryan spent in May less than April
= 660 - 480
= $180 (x)
The month that Bryan spent $160 more than the previous month = Apr
Answer(s): (a) $372; (b) Apr
